Azido polymers find use as energetic binders in a variety of composite explosive and propellant applications, but few azido polyesters have previously been reported: a method is introduced for the preparation of two azido polycarbonates, poly(2,2′-bisazidomethyl-1,3-Pr carbonate) and poly(3-azido-1,2-Pr carbonate), possible binder candidates for energetics applications. The preparation method for these polymers involves a two-step synthesis starting from the bulk polymerization of the com. sourced diols with di-Ph carbonate in the presence of lanthanum (III) acetylacetonate as a neutral catalyst, and subsequent azidation in cyclohexanone. The phys. and thermal characteristics of each are reported, indicating properties similar to other azido-polymers. The thermal and mech. properties of cured azido polyester resin mixtures are the subject of ongoing research. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Reference of 102-09-0).
Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Reference of 102-09-0
